DANIEL D. JAMES, OF MATTOON, ILLINOIS.

'ELL-STRAINER. t

To all 'whom it may concern:

Be it known that I, DANIEL D. JAMES, a citizen Iof the United States,and a resident pf Mattoon, in the county of Coles and State of Illinois,have invented a new and Improved "Well-Strainer, of which the followingis a full, clear, and exact description.

My invention relates to a new and improved form of well strainer andeasing, and more particularly pertains to that class of well casingswhich are adapted to be sunk into sand strata, to collect thesubterraneous water.

.'An object of my invention is to provide a casing which may be sunkinto the ground, said casing having closed port closures, which may bereplaced by an improved form of screen.

I attain the above-outlined object by constructing a metallic cylinderhaving elongated ports in the side adjacent the` lower end, which portsare first close'dby solid gates, which gates are replaced by gates inthe form of strainers.

With the above and other objects in view, as will more fully hereinafterappear, the

resent invention consists in certain novel etailsof construction andarrangement of parts hereinafter'fully described, illustrated in theaccompanying drawings, and more particularly pointed out in the appendedclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatedcorresponding parts in all the gures, and in which-- Figure 1 is avertical sectional view showing the lower end of my improved casing;Fig. 2 is a transverse sectional 'view taken A through the side of thecasing and one of the ports; Fig. 3 is a transverse view taken on theline 3--3 of Fig. 1 and looking in the direction of the arrow; Fig. i isa detailed front elevation of a solid gate; Fig. 5 is a View similar toFig. 4, but showing the gate in the form of a strainer; Fig. 6 is a viewsimilar to Fig.- 5, but showing the same reversed; Fig. 7 is atransverse sectional view taken 0n the line 7-7 of Fig. 5.

In the several figures I have shown a eylindrical form of easing 10having a detachable bottom 11, through which projects the common form ofsuction pipes 12, said suctionpipe 12 being used to draw the loose:material up from the outside and bottom of Specification of LettersPatent.

the casing, as is common with constructions of this character. Disposedcircumferentially about the side of the casing 10, a. short distanceabove the bottom thereof, is a series of longitudinally-extending ports13, and within the cylinder and disposed on op' posite sides of theports 13 are pairs of guideways 14, which guideways have alined slots 15in which are originally disposed and adapted to slide, solid gates 16.The upper end oi each of these gates has extended from the rear thereof,a boss 17, to which is attached a flexible member 18, by means of whichthe gate is withdrawn from the casing after it has been removed from theguideway 14, as hereinafter described. The bosses 17 are perforated inorder to attach the vertically movable screw-threaded rod 32 to the gate16, should it be desired to manipulate said gate by a. rigid or strongerconnection than is afforded by the flexible members 18. l

Resting upon each of the gates 16, positioned above the same and carriedin guiding blocks 19, is a series of sliding screens 20, so disposed inline with the alined slots 15, that when each screen 20 is lowered, itwill displace the gate 1G from said alned slots. In order to actuatethese lscreens, there is extended from the rear face of each of thesame, a lug 21 carrying a verticallymovable screw-threaded rod 22inserted in a screw-threadedfbloek 23 and actuated bv a lever 24. Thescreens are recessed longitudinallyyas shown at 25, and have extendingabout these recesses, `a depressed shoulder 26, upon which shoulder isdisposed a series 4of spaced apart longitudinally extending plates 27fastened to the shoulder 26 by means ot' screws28, and so disposed as toalord 'a variable opening 29 between the several plates, so as to permitthe iniiow of water but to prevent the passage of grains could be madewithout departing from the scope thereof. It is intended that allmatters contained herein, in the above description or shown in theaccompanying drawings, shall be interpreted as illustrative and' not .ina limiting sense except as embodied in the claims.

Having thus described nmy invention, I

` isin position.

2. In a well strainer havlng a series of clalm as new and desire-tosecure by Letters Patent:

1. A well strainer comprising a cylindri-V cal casing having a series ofopenings therein, a sliding gate normally closing eaeh of said openings,and a sliding strainer adapted to displace each of said gates when thecasing the strainer is opened to permit the entrance of fluid therein,and means lwhereby the 15 extent of said opening is regulated.

3, A well strainerycomprising' a casing having a series of openingstherein, means4 normally closing each of said openings, and

a strainer adapted to displace each of said 20 'l `pies of this patentmay be obtained for five cents each, by addressing the Commissioner ofPatents, Washington, 1),'0.
